Maybe we need an extremely strong and centralized non-profit with their own Reddit/Twitter/etc. clone. As long as it’s open data and open source, I don’t really care that it’s centralized. We need some entity with enough resources and trust so they can fend of corporate takeover. My vote is Wikipedia, Mozilla, or Linus Torvalds (I want the man himself, not the Linux Foundation).
We have tried this, and its even worse, look at signal adoption on iOS if you want an example of how that went.
